Specification of Letters Patent.

Patented May 7, 1918.

Application filed February 9, 1917. Serial No. 147,653.

To all whom it may concern:

Be it known that 1, JOHN C. EUBANK, a citizen of the United States, residing at Gampbellsville, in the county of Taylor and State of Kentucky, have invented certain new and useful Improvements in Scythes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the class of harvesters, and more particularly to a scythe.

The principal object of the invention is the provision of a scythe embodying a handle and a blade, novel means being provided for detachably connecting the blade with the handle.

Another object of the invention is the provision of a coupling member including a socket adapted to receive the blade shank, the shank being securely fastened to the coupling member, and a handle having a tubular open end adapted to receive the socket and be securely attached upon the coupling member.

A further object of the invention is the provision of a pliable pipe handle having detachably connected to one end thereof a scythe blade, said pliable pipe permitting of the handle to be bent in any desired shape.

A still further object of the invention is to improve and simplify the construction of devices of this character, so as to be reliable and efiicient in use, of comparatively inexpensive construction and of durable and substantial design.

With these and other objects in view as will appear as the description proceeds, the invention comprises the various novel features of construction, combination and ar rangement of parts as will be more fully described hereinafter, and set forth with particularity in the appended claims.

Referring to the drawings,

Figure 1 represents a side elevation of my improved scythe.

Fig. 2 is a vertical longitudinal section taken on the line 22 of Fig. 1.

Fig. 3 is a detail perspective view of the coupling member.

Fig. 4: is a plan view thereof,

Fig. 5 is a detail plan view of the scythe blade shank, and

Fig. 6 is a detail plan view of the forward end portion of the scythe.

Fig. 7 is a fragmentary side elevation showing another form of coupling member arranged in operative position.

Fig. 8 is a longitudinal sectional view taken on the line 8-8 of Fig. 7.

Fig. 9 is a detail perspective view of the coupling member.

Fig. 10 is a detail perspective view of the U-bolt clamp.

Similar characters of reference are used to denote like parts throughout the accompanying drawings and the following description.

Referring more particularly to the drawings, my improved and novel construction of scythe is shown to consist of the usual blade 1 having a tapered shank or heel portion 2 that is provided with an aperture 3, the purpose of which will presently appear.

The tapered shank 2 is adapted to be inserted within a socket 4 for frictional engagement therewith, said socket being carried by a coupling member 5, and in this instance I have preferably shown the socket member formed integral with and upon the forward thickened portion 6 of the coupling member, this latter thickened portion being provided with an aperture 7 extending vertically therethrough which in this instance is shown to be square for a purpose to be presently set forth. The rear and greater portion 8 of the coupling member 5 is slightly less in thickness than the forward portion as clearly shown in Fig. 3 of the drawings, and the rear end portion thereof is provided with an aperture 9, which in this instance is shown to be square.

In assembling the device and after the tapered shank 2 has been inserted within the socket 4,, a securing bolt 10 having a non-circular or square shank is inserted upwardly through the aperture 7 of the coupling member and through the aperture 3 of the shank, the bolt being further provided with a nut whereby the shank 2 may be rigidly and securely held in position within the socket and upon the forward thickened portion 6 of the coupling member.

I further provide a handle 11, which is preferably constructed of a hollow piece of pliable pipe having its forward end portion slightly reduced as indicated by the nunieral 1:2, and flattened on its under side as indicated by the numeral 12 and formed with an upturned end 18. The handle is further provided with an aperture it slightly in rear and adjacent the forward reduced portion 12. ln further assembling the device, the hollow handle 11 is positioned upon the rear port on S of the coupling member and moved iorwardly thereon until the rear end of the tapered socket t is positioned friot-ionally within the hollow reduced end 19, or in other words until the upturned end 13 substantially flush against the shoulder 15 formed by the (litterence in thickness between the torward and rear portion T and S of the coup ing ineinber. lhe coupling i'neinber is also provided on opposite sides and adjacent the shoult er 1:") with apertures through which are designed to be passed the lower ends of a bolt 17 that embraces the forward end por- V icing prorided with able 18 w l i eby the forward end por tion 12 of the aandle may be securely clamped and retained in position upon the coupling nieniben ln order to securely attach the rea end oi? the portion 8 the handle, a securing bolt 19 having a squared shanlt is passed up wardly through the aperture and through the aperture t l of the handle, the upper end thereof being provided with a clamping nut 20 whereby the handle may be securely and etlectively attached to the coupling memher.

The handle 11 is provided with hand grips 21 whereby the scythe may be readily, grasped in order to manipulate B37 male ing this handle 11 of a piece of pliable or bendable pipe it will be possible to bend the handle into any desired shape, or to that shape which is found niost'conrenient to the particular person using; the scythe.

In Figs. 7, 8 and 9 will be seen another way in which my improved coupling incinber 5 may be rnade This particular coupline; member 5 is shown to consist of a rearwardly extending concave convex supporting; arm 22, that'is formed adjacent its rear tion of the handle immediately in rear of the upturned end 13 iJlUZI'GOl the lower ends of the bolt i suitend portion with a

non-circular aperture

23, and 15 formed achacent its forward end with a pair of apertured ears disposed diainetrically opposite to one another.

The forward portion of the coupling member is enlarged and is formed with a rearwardly extending reduced circular estension 26 that is disposed concentricallv ot the concardconvezr supporting" arm. his

52'? designed to receive the tapered shank or heel portion :2 oi the scythe blade 1.

Extending from the lower forward por tion of the enlarged portion is an apertured car 28, the upper surface of which lies in the same plane the bottom of the socket 2?, while the lower surface lies in the same plane with the bottom of the coupling member. As shown the aperture extending through the ear 28 is non-circular and is designed to receive a carriage bolt 29 or handle receives the reduced circular extension 26, this extension 26 being so positioned that when it is disposed within the end of the pipe handle, the latter will restin the concave-center; supporting arm. The pipe handle provided with a pair of diametrically opposite apertures designed to re ceive the shank of a carriage bolt 33 or other similar bolt having a squared shoulder, which bolt is passed upwardly through the non-circular aperture ot' the supporting arin anl is proviced on its upper end with re ning' not 34 whereby the handle may be securely clamped to the coupling member. 7 V

In order to rigidly retain the forward end portion of the handle in position in a more secure manner, l provide a shaped clip bolt which embraces the pipe handle and has its arms extending downwardly through the ertured ears and are each provided a retaining nut 36, whereby the exerne end portion of the pipe handle may be securely fastened to the coupling member in an opeatire position.

If found desirable the concave-convert supporting" arm 22 may be made slightly wider. as for instance it a scythe were being; used that had a wooden handle and the sarne should become worn or loose in its connection with the blade, the wooden handle can be removed from the blade the end cut off and a hole bored in the end large enough to receive the reduced circular extension 26. from which it will be seen that the wooden handle can be inserted over the extension 26 so as to rest in position upon the concave COHVQX supporting arm, where it may be secured in position the same way that the pipe handle is secured.

From the foregoing description it will be apparent that l have provided a novel construction of scythe wherein the rario'" s parts will be etecti h l securely inaiiained in their respective position, and one which is of durable and substantial design, and of cheap and inexpensive construction. By using bolts having square shanks, they will be prevented from turning and thus eliminate any tendency to cause the adjacent parts which they connect together from becoming loose and causing an undue amount of wear between the parts.

What I claim is 1. A scythe comprising a blade having a tapered shank, a coupling member, a socket carried by said member intermediate its ends and adapted to receive said tapered shank, means for securing said tapered shank to the coupling member, a tubular handle adapted to be positioned on the coupling member and receive one end of said socket, and means for securing said handle to the coupling member.

2. A scythe comprising a blade having a tapered shank, a coupling member consisting of an enlarged forward portion having a reduced extension, both of which are formed with a single tapered socket, an apertured ear extending from said enlarged portion adapted to cooperate with said socket to support said tapered shank, securing means extending through said ear and shank, the rear end portion of said coupling member consisting of a concavo-convex supporting arm, said reduced extension disposed concentrically of said supporting arm, a pipe handle adapted to be engaged over said reduced extension and rest in said concavo-convex supporting arm, and means for securing the pipe handle to the coupling member.

3. A scythe comprising a blade having a tapered shank, a coupling member consisting of a forward portion having a reduced extension, both of which are formed with a single tapered socket, an apertured ear extending from said enlarged portion adapted to cooperate with said socket to support said tapered shank, securing means extending through said ear and shank, the rear end portion of said coupling member consisting of a concavo-convex supporting arm, said reduced extension disposed concentrically of said supporting arm, a pipe handle adapted 0 to be engaged over said reduced extension and rest in said concavo-convex supporting arm, a U-bolt embracing said handle and extending through said ears, nuts for the free ends 01 said U-bolt, and a clamping bolt disposed through said handle and the rear end of said supporting arm.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
